Fishing Tools Reverse Circulation Junk Basket

The Reverse Circulation Junk Basket from Dongying Lake Petroleum Technology Co., Ltd is designed to capture small debris such as drill cuttings, tool fragments, and casing shards during wellbore cleanout operations. The tool operates by creating a reverse fluid flow path when a steel ball is dropped into its internal valve, directing debris upward into the barrel above the catcher mechanism. The barrel diameter is 3.5 inches, with a standard length of 72 inches, and the valve seat is precision-machined to accept a 2.5-inch steel ball.

Typical industry standards for reverse circulation junk baskets include a perforated lower section with 0.5-inch diameter vents to allow fluid flow while retaining solids, and a magnet insert option for ferrous debris. The tool body is made from high-strength carbon steel with a minimum yield strength of 60,000 psi, suitable for use in deviated and horizontal wells. The valve mechanism is spring-loaded and designed to reset automatically after each circulation cycle, reducing the need for manual intervention.

These tools are commonly purchased by drilling contractors operating in the Bohai Bay, Tarim Basin, and other regions with high debris accumulation during drilling. Buyers typically order in quantities of 3 to 10 units per job, packaged in protective steel tubes with threaded caps. Trade terms are negotiable, with common arrangements including FOB Tianjin or CIF Middle East ports. Payment is usually via T/T, and lead times for standard units are 3 to 4 weeks. Custom modifications, such as extended barrels or magnetic inserts, require additional confirmation.
